GUARDIAN® Revision Hinge
 
 
Wright Medical Technology, Inc.
The resurfacing femur design allows for only 28mm of femoral bone resection and is available in a wide range of sizes that promote optimal prosthesis fit. The constrained design precludes the need for a patellar component. The prosthesis consists of a femora stem, resurfacing hinged femur/tibia, axial pin, polyethylene spacer, tibia sleeve, and an optional tibia stem extension.
